Specification of Letters Patent. Application filed Septemhetll, 1909.

To" all'wiwm it may concern:

Be it; known that I, Minimal. AI Dnorrcoon, of Chica o, in the county ofCook-and State of Illinois, have invented certain. 'nenand usefulImprovements in Inking Appara tus for. Printing-Presses; and I'.l1erebydcclare that the following is a full, clear, and reference being had tothe accompanying drawings, which form part of this specification.

This invention is i'ng mechanism for oh cct is to regulate plied fromthe roll and duration of contact between the ductor roll and thefountain roll can bevaried, so be taken by the roll according toprinting presses and its the amount of ink supducto'r from the fountainThe. invention consists in"v.ery simple, ef-

ficient and novel means for accomplishing 'this object as hereinafterdescribed. and a preferred .form "of mechanism embodying the inventionis illustrated in the accompanying drawings in which:
